AENT OFFICE JOHN ARMSTRONG MCANULTY, OF INDIANA, ASSIGNOB OF ONE-HALF HIS RIGHT TO HENRY O. BEAMER, OF CENTRE HALL, PENNSYLVANIA.

IMPROVEMENT IN ELEVATORS AND CONVEYERS.

Specification forming part of Letters Patent No. 1 7 1,550, dated March 7, 1876; application filed February 16, 1876.

To all whom it may concern:

Be it known that I, JOHN ARMSTRONG Mo- ANULTY, of Indiana, in the county of Indiana and State of Pennsylvania, have invented certain new and useful Improvements in Elevators and Gonveyers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a hay-elevator, as will be hereinafter more fully set forth.

In order to enable. others skilled in the art to which my in vention appertains to make and use the same, I will now proceed to describe its construction and operation, referring tothe annexed drawings, in which- Figure 1 is a longitudinal section of a barn, showing my hay-elevator in position therein. Fig. 2 is a cross-section of the same. 'Fig. 3 is an enlarged section of the coupling for connecting the fork-pulley and elevator. Fig,,4 is a section through the center of a wooden pulley in the carriage.

A represents a barn or hay-house, of any suitable construction, at one end of which, in the center, is fastened a rod, B, by means of an eye-bolt, a, as shown in Fig. 1. At the other end across the barn is secured a rod, 0,

- which may run parallel with the rafters-that is, elevated in the center and sloping down toward both sides, as shown in Fig. 2or it may be run horizontally across, or in any other suitable manner, to receive the other end of the rod B, which has a frame, 1), fastened thereon. In this frame is mounted a pulley, D, to run on the rod 0, which allows of placing this end of the rod B at any point desired between the two sides of the barn, and as the carriage runs on said rod the hay may thus be distributed equally in all parts of the mow. E represents the carriage, constructed in any suitable manner, with rollers or wheels d d in the upper part to run on the rod or track B. In the front part of the carriage E is pivoted a hook, G, by means of a pin, z, passing through a slot, e, in the hook. The outer or front end of the hook G is to catch on a stationary catch, f, placed on the rod B, in order to hold the elevator in place while raising the hay from the Wagon. On the inner end of the hook G is hung a stirrup,

H, the lower end of which is coupled to a' per end, is provided with a cup-shaped rim, M. The carriage is drawn down to its place by means ofa weight, N, attached to a rope, m, that passes over a pulley, a, and is fastened to the front end of the carriage. The hoisting-rope O is also fastened to the front end of the carriage, then passes around the fork-pulley K, over a wooden pulley, P, in the higher bottom corner of the carriage, and from thence around a pulley, p, at the upper end of the track, and then around suitable pulleys to the horse. The fork being loaded,

the horse is started, and when the fork is elevated until the rim M passes over the lower end of the tube I, a pin, 8, projecting verti cally upward from the frame L, strikes the plate In, and thereby releases the hook G from the catchy. At the same time the hooks J J catch on the under edge of the rim M, and thus suspend the load. The carriage then travels up the rod B until it reaches the upper end, when the fork-pulley frame is slightly raised till the pin 8 strikes the plate is and trips the hooks J J, allowing the fork to descend; or the fork may be unloaded while suspended by the use of the ordinary'triprope, and when the carriage is drawn down by the weight N, and the hook G is caught by the catch f, the movement of the hook G will trip the hooks J J, and release the fork-pulley frame, and allow the fork to descend. The wooden pulley P revolves upon a hollow journal, it, having pointed ends, which fit in corresponding depressions x on the inside of the carriage E, and a bolt, o, passes through said journal, and when tightened draws the carriage tight onto the ends of the journal, holding it firmly in place in such a manner as to prevent the journal splitting.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hay-elevator, the rod or tra :k B, held stationary at one end, and provided at the other end with a pulley operating on a cross-rod, substantially as and for the purposes herein set forth. v

2. The combination of the rod or track B, frame I), with pulley D, cross-rod G, and eyebolt a, all as and for the purposes set forth.

3. The combination of the hook Gr, stirrup H, tube I, hooks J J, and plate 70 with the fork-pulley frame L, rim M, and pin 8, substantially as and for the purposes herein set forth.

4. The combination of the carriage E, having depressions w, wooden pulley P, hollow journal t, with pointed ends, and the bolt 41,

substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own'iuvention I afli'x my signature in presenoe of two witnesses.

JOHN ARMSTRONG MCANULTY.
